Sleep Satisfaction and Intentional Self-Awakening: An Alternative Protocol for Self-Report Data

We have reported that sleep satisfaction provides an effective research variable for use with large groups. It affects self-report measures of waking behavior, time spent in bed, and both spontaneous and intentional awakenings from sleep. Here, we report that with a counterbalanced design and self-awakening requirements meant to be more difficult for the subjects to attain, systematic differences were, again, found for the sleep-satisfaction groups. Self-reported sleep satisfaction is an heritable behavior. The genetic and environmental implications are discussed.
